Fig. through rotor and impingement-rings, having inturned tips on both impingement-rings over the rotor close to the center of the rotor.

As illustrated in the simplest form of Fig. 1, for the supply coming through the inlet connection 1 of the main housing 8, an escape is provided through the several openings 9. About this portion of the housing, and in cooperative relation to these openings, are the jet-rings I0 and the rotor I I.

The cap I2 serves to close the upper end of the housing, and, with its enlarged front edge I3, serves to clamp the several operating rings, excepting the rotor, against the shoulder I4 of the housing.

For a more perfect and smooth operation, there are also a central guiding-ring I5 and outer defiecting-rings I5.

Nozzle-jets I1 are made as mere impressions in the face I8 of the jet-rings I0. Any fognozzle is provided with at least one pair of these rings, the pair being placed face to face in operative position.

The pair of jet-rings is preferably always keyed in proper position on the main housing B, as indica-ted at 2l in Fig. 1, to always retain its properly aligned position with respect to the openings 9 in the housing.

In order to be actuated by the nozzle-discharges, the inner faces of the rotor are provided with pockets or notches 22, indicated in Figs. 1 and 10.

Any escape, by way of the openings 9 in the housing, to result in a discharge from the jets I1, to act upon the rotor by means of the pockets 22, is made to pass through the passages 23 in the defiecting rings I6 outwardly beyond the rotor.

In this action of being flung, or centrifugally thrown outwardly, the discharge is deflected upon, or along the front face 24 of the rotor by the outermost edges 21 of thedeflecting-rings I6, to .be finally impinged from opposite sides over the outermost front edge 25 of the rotor.

A vaporizing is thus accomplished by repeated breaking up of the passing matter in its path through the housing and rotor; rst being divided through the several openings El; secondly being forced through the narrow, flattened jetends I1; thirdly being forced against the pockets 22 of the rotor; fourthly being defiected through the passages 23; fifthly being deflected by the ring-edges 21; and, finally, being impinged over the front edge 25.

The passing of matter from the opening 9 to 14 is a fragmentary vertical section the jet-ends I1 should be clear from the illustration in Fig. 1, where it is indicated that the j et-end 51a is flattened and broadened to a width, to easily pass the ring l 5. This feature is, moreover, made clearer by the illustrations in Figs. 2 to 8; particularly, Figs. 3, 5, 'I and 8, where the widening space of the nozzle-jet 11a is amply clearing the ring I5.

The simple device, illustrated in Fig. 1, may be said to deliver a definite amount of discharge in a certain manner, when once assembled; which may be changed only by inserting packing marterials of diierent thicknesses in the different joints between the several rings.

On the other hand, the arrangement of Fig."

9 allows many adjustments with the same assembly, to be handled by any unskilled person under directions of the manufacturer, and to be realized from easily readable indicators on the device.

' Of course, all sorts of make-shifts can be made for getting variations in the resulting spraying. Jets in lower or upper ring-halves can be made of slightly different sizes so as to get a stronger spray in one or another direction. Ring-halves can be packed so as to produce more or less discharge to one or the other of the rotor-halves, so as to get or have a larger or smaller discharge from one side or the other over the front or outer faces of the rotor, to, thereby, cause the impingement over the front-edge 25 to be stronger one way or the other, upwardly, or downwardly. All such makeshifts, however, are only troublesome.

Nevertheless, it can be of great advantage, when it is required or desired to have a fog discharged in certain directions or to have it hang or remain in certain places predominantly; to have for such various purposes certain and definitely operating means by which to get such results at will.

Extra, definitely operating adjusting means are therefore provided in the modification illustrated in Fig. 9. Adjustments for such predominance are provided at the very exit of the discharge; the adjusting-rings 28. having overreaching edges 29 for controlling the passages 23, and these over-reaching edges may, of course, extend closer to the very front edge 25, 29a indicating such condition in Fig. 14. The impingement may thus be controlled more closely to the very nal discharge from the nozzle. Predominantly forceful discharge may thus also be diverted upwardly or downwardly to suit requirements. The lock-rings 30 serve to maintain the rings 23 in adjusted position. Pointers 3| are provided on the lock-nuts or rings 3D, to indicate predetermined positions by means of graduations, easily provided on the front edge at 32, though not particularly illustrated in the drawing since that sort of thing is well enough known to not necessitate further showings.

These rings 28 and 30, thus mounted adjustably on the extensions of the modified deflectingrings |611, may be set in predetermined positions for definite larger or smaller discharges on one side or the other of the rotor, or in positively equal forces, to assure any desired results.

The outermost edge 25 may be a part of the rotor, as described herebefore, or it may be a, part of the ring I5, the ring I5a being thus modified, to extend through the rotor. Fig. 12 illustrates another slightly modied form in ring I 5b, in which a pin V2t) connects the-two rotorhalves IIb with the vring for uniform rotation.

s Fig. 13 illustrates still anotherslightly modified form |56 which is provided with a diverting portion 26, to overlap the innermost edges of the rotor-halves, for diverting the passing stream in such a manner as to not force itself too strongly Y halves, and embodying the portions 26, to prevent undesired leakage between the several rings, thereby bringing the pressure to the opposite side of the rotor to the utmost; and connecting the rotor-halves for joint operation as in Fig. 12.

From the foregoing, it will be understood that the rotor-halves can be made to operate in distinctly different circulating or rotating directions by the mere application of suitably co-operating nozzle-halves.

Having stipulated in the foregoing preamble a making of the nozzle-rings by the die-casting process, it serves to facilitate the most accurate shaping of even diflicult nozzle-orifices or passages at the least cost for their manufacture, and the safest and surest application of the proper, or even any, nozzle-rings by even any unskilled person for the most efficient and practical use.

It is definitely possible to make, either the application of the nozzle-halves in the manner illustrated in Fig. 2, or ,the extremely opposite application of the nozzle-halves in the manner illustrated in Fig. 6, most effective and efcient under different conditions and for different pur'- poses, though under and with very similar construction for and of the whole or complete fognozzle.

From this, it then follows that, if both rings of a pair are provided with jet-impressions of the same design, both jets, either, in the form of Fig. 10, or in the form of Fig. 11, the jetoutlets ypointing in one and the same direction when looking at the upturned faces of such rings, the effect of the pair is that the combined jetoutlets, or orifices, will point in opposite directions when such a pair isk placed face upon face as illustrated in Figs. 2, A3, 4, and while, on the other hand, if one of the rings of the pair is provided with impressions as illustrated in Fig. 10, and the other ring of the same pair is provided with impressions such as illustrated in Fig. 11, this arrangement will result in a combined nozzle and jet system in which oppositely placed rings, face to face, will form co-operating joint-jets, with each pair of jets in both rings of the pair pointing in the same direction, as illustrated in Figs. 6, 7 and 8.

This idea is made use of for different purposes. For instance, it may be the principal object, and therefore desired and required in a certain project, to provide for the greatest amount of discharge, regardless of anything else; in which case the joint operation of both jet-rings of the pair in the same direction may satisfy best, inasmuch as they operate against the least reslstance, and, simply forcing both the rotorhalves to the greatest speed possible, to result in the greatest centrifugal force, by which to discharge the greatest volume possible, though the impingement may not be very strong, since the discharges from opposite sides of the rotor 6 will be at such an acute angle as to be rather parallel tangentially to the rotor, due to the joint, and joined, equally rotating centrlfugally discharging action.

For another purpose, on the other hand, the impressions may be made to appear alike when looking at the upturned faces in the pair of jetrings, which would cause the rings, when turned and placed face to face, to discharge in opposite directions, which, in turn, will create and cause forces to act differently on oppositely disposed rotor-halves, whereby the discharge from one side of the rotor will be impinged against the discharge from the opposite side of the rotor, not only by reason of they angular meeting over the outer faces of the combined rotor-halves but, additionally, by reason of the oppositely rotating centrifugal discharges from the oppositely actuated rotor-halves, really acting tangentially against one another, thereby resulting in a more forceful impingement over the front faces of vsuch rotor-halves, though it may lower the speed of the rotor-halves and therewith lower the amount of discharge, compensated for only by applying greater operating force.

That the discharge from any jet is not materially impaired by the somewhat surrounding arrangement of the central ring I5, as might erroneously be believed from the illustration of Fig. 1, is made clearer by the illustrations in Figs. 3, 5, 7 and 8. Particularly Figs. 5 and 8 show quite definitely that the broadening and flattening of the jet is sufficiently spread before it reaches the ring l5 at the points A and B, see also, and compare with, Figs'. 2 and 6, so that the discharge may easily reach the orifice Ila, which is also indicated in Fig. 1. The section-lines R-R and L-L in Fig. 6 give a more definite line of section on which Fig. 1 is taken; L merely designating the left'side of Fig. 1, while R designates the right side of Fig. 1. The portions 26 of the modified form vof ring I5.; in Fig. 13 are made at an angle practically predicated by the slant of the jetas illustrated in Figs. 5 and 8, so that such portion also does not impair the passage to any degree materially, but the shoulders so gained can close any eventually existing gap between the rings, thereby serving to guide the passing liquid so much more over the outside faces of the rotor.

Holding and guiding the rotor in a central position not only provides the best operating conditions for the rotor itself, but, moreover, maintains the equal spacing over both sides of the rotor, as at 23; and a free and most speedy rotation of the rotor helps to keep the passages clear to the extent that such operation practically frees itself of clogging particles.

The large, bowl-like, housing 8 serves as a pressure equalizing tank, eliminating air-pockets that are frequently encountered in supply lines, and this housing, also, provides a space for the insertion of a filter ahead of the nozzles withoutv choking the ilow through the device towards the nozzles or jets. In fact, the whole bowl may easily contain a filtering medium with suitable screens, to assure proper operation of the whole fog nozzle.
